In the reaction between an acyl halide and an alcohol the thermodynamically favoured prodtcts are the free carboxylic acid and the alkyl halide. The initial reaction is, generally, the formation of an dster and HHal. Vhen the alcohol is very prone tn yield an alkyl cation upon protonation ...
third, you have an alcohol and not an alkyl halide what do you need to know about SN1 and SN2? note: butyl alcohol with H2SO4and heat will most probably go E2 Hi, Okay let's see if I understand. Acids like to give protons, in the equation I should show this. The equation should...
Evidence for this mechanism is as follows: The addition of pyridine to the mixture of alcohol and thionyl chloride results in the formation of alkyl halide withinvertedconfiguration. Inversion results because the pyridine reacts with ROSOCl to give ROSONC5H5before anything further can take place. Th...
Alcohol derivatives can also be alkylated to yield ethers derivatives: for example, using analkyl halide(the Williamson ether synthesis) ROH+R1X → ROR1 Alcohols are also good alkylating agents in the presence of suitable acid catalysts. For example, most methyl amines are prepared by alkylation ...
Refluxing 2-cyanomethylbenzimidazole in alcohol with alkyl halides led to low yields of N-alkylated products. Addition of base to the reaction mixture shifted the course of the reaction to form mainly N,C-dialkyl substituted products. In DMF or with an excess of alkyl halide at elevated ...

Alkyl halides can be prepared by addition of the halogen or hydrogen halides to alkenes, as well as by substitution of a halogen for hydrogen in an alkane. The most important method of preparing alkyl halides is by reaction between an alcohol and a hydrogen halide. View chapterExplore book ...
